ABSTRACT:
A method for dividing a signal having a first frequency by a divide ratio includes selecting, based on the divide ratio, a first pulse width of at least one signal having a second frequency and being generated by at least a corresponding one of a plurality of pulse-width control circuits responsive to at least one signal having a second pulse width. The method includes selecting at least one of the plurality of pulse-width control circuits to be powered-on to generate the at least one signal. The at least one of the plurality of pulse-width control circuits includes a first pulse-width control circuit to generate a first signal having the first pulse-width, second frequency, and first phase. The first signal corresponds to a select circuit output signal having a first phase. The method includes selecting at least one other of the plurality of pulse-width control circuits to be powered-off.
